to letters or figures of reference marked thereon, which form a part ofthis specification.

Figure 1 of the drawings is a top view of streetcar body with myimprovement attached. Fig. 2 is a bottom View of my improvedanti-friction attachment. Fig. 3 is a side elevation; Fig. 4, a verticallongitudinal section of valve-chamber. Fig. 5 isa modified View of myanti-friction attachment. Fig. 6 is a vertical longitudinal section ofvalvechamber.

This invention is a device for throwing water, oil, or other properlubricating liquid on a railway-track when turning a curve, to reducethe friction and prevent the flange of the wheel that is forced againstthe outer rail of the curve from being cut-or from cutting the rail; andit consists in the construction and novel combination of parts, ashereinafter set forth. The device is applicable both to street and steamrailways.

Referring to the accompanyingdrawings, A. A designate the outer andinner rails, respectively, of acurve on a railway.

B is the body of astreetcar, and G the tank to contain water or oil,placed in a convenient position thereon.

e is a pipe connecting the valvechamber E to the tank, and F is avalveof proper con struction within said chamber and resting on a seat formedby the adjoining end of the pipe e. The valve-rod fpasses out of thehead of the chamber E, and its portion outside of the chamber isprovided with a hook, f, having one end of a coiled spring, G, attachedto it, the otherend of which is attached to a hook,f,

- fixed to a bracket secured to the car-frame.

cally, and then extending rearwardly over the rails A A, the said pipesbeing supported by brackets secured to the car-frame on each side.

To a smallsupport on the platform of the car is journaled the treadle I,having a depending arm, 2', pivoted at its end to the adjacent end ofthe vaIve-rodf.

In turning a curve, when the driver wishes to throw the lubricator onthe track, he presses down the treadle, and by means of the arm thereofpulls the valverod outward against the spring G and moves the valves soas to allow communication between the pipes eand H. The lubricatingliquid then flows out through the valve-chamber and pipes H upon therails. After the treadle is released it is raised by the retracting ofthe spring G,which also causes the valve F to cutoff communicationbetween the pipe H and the pipe 6, thus preventing the outlet of thelubricator. The lubricator prevents the grinding action between theflange and outer rail of the curve, and the momentum of the car or traincarries the same around the curve.

Upon locomotives a modification (shown in Figs. 5 and 6) is used. Inthis the lower arm of the treadle is connected by a link-rod, I, to thedepending arm of an angle-lever, K, which is pivoted at its anglebetween lugs depending from an extension ofthe valve-charnher. The valvealso (Fig. 6) has a vertical motion, and has its part below thevalve-chamber surrounded by a coiled spring, the equivalent of thespring G, which bears against a pin, 9, to keep the valve closed on itsseat. The point of the valve-rod bears upon the horizontal arm of theanglelever K, so that when the engineer or fireman depresses the treadlethe valve is pushed upfrom its seat and thelubricator from the:tankallowed access to the discharge-pipes.

Having described my invention, I claim 1. The combination, with thecar-body and wheels having their axles connected to the body in theusual manner, of the tank secured to the car-body, the valve-chambercommunieating by a pipe, e, with the tank, the pipes a,running from thevalve-chamber,and having their discharge-orifices over the rails infront or outward from the adjoining wheels, the pisthe treadle journaledupon brackets secured I00 ton-rod F and its reciprocatory valve-rodf,

to the car-platforms and acting substantially as described upon thevalve, and the spring G, whereby the val vc-rod is moved in thedirection opposite to the motion imparted by the treadle when releasedfrom the latter, substantially as specified.

2. The combination, with the car body, wheels, and tank secured to thecarbody, of the spring-elevated treadle I, attached to the platform ofthe car and provided with the depending arm '5, the valve-chamber'E, thepipe 6, connecting the tank and valve-chamber, the pipes H, thepiston-valve F and its stem f,

the spring G, surrounding the end part of the valvestein, the angleleverK, and the linkrod 1, having its lower end adjustable on the dependingpart of the angle-lever, all construeted and arranged substantially asand for the purpose specified.

In testimony whereof I affiX my signature in the presence of twoWitnesses.
